1. Summary:

Updated netpbm packages that fix two security issues are now available.

This update has been rated as having moderate security impact by the Red
Hat Security Response Team.

2. Relevant releases/architectures:

Red Hat Enterprise Linux AS (Advanced Server) version 2.1 - i386, ia64
Red Hat Linux Advanced Workstation 2.1 - ia64
Red Hat Enterprise Linux ES version 2.1 - i386
Red Hat Enterprise Linux WS version 2.1 - i386
Red Hat Enterprise Linux AS version 3 - i386, ia64, ppc, s390, s390x, x86_64
Red Hat Desktop version 3 - i386, x86_64
Red Hat Enterprise Linux ES version 3 - i386, ia64, x86_64
Red Hat Enterprise Linux WS version 3 - i386, ia64, x86_64

3. Problem description:

The netpbm package contains a library of functions that support programs
for handling various graphics file formats.

A stack based buffer overflow bug was found in the way netpbm converts
Portable Anymap (PNM) files into Portable Network Graphics (PNG). A
specially crafted PNM file could allow an attacker to execute arbitrary
code by attempting to convert a PNM file to a PNG file when using pnmtopng
with the '-text' option. The Common Vulnerabilities and Exposures project
has assigned the name CVE-2005-3632 to this issue.

An "off by one" bug was found in the way netpbm converts Portable Anymap
(PNM) files into Portable Network Graphics (PNG). If a victim attempts to
convert a specially crafted 256 color PNM file to a PNG file, then it can
cause the pnmtopng utility to crash. The Common Vulnerabilities and
Exposures project has assigned the name CVE-2005-3662 to this issue.

All users of netpbm should upgrade to these updated packages, which contain
backported patches that resolve these issues.

4. Solution:

Before applying this update, make sure all previously released errata
relevant to your system have been applied.

This update is available via Red Hat Network.  To use Red Hat Network,
launch the Red Hat Update Agent with the following command:

up2date

This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.

5. Bug IDs fixed (http://bugzilla.redhat.com/):

173342 - CVE-2005-3662 netpbm off by one error
173344 - CVE-2005-3632 Netpbm buffer overflow
